Parrotfish are named so because they have lots of tiny teeth packed tightly together on the outside of their jaw, forming a parrot like beak. They use this beak to consume algae and coral. Parrotfish are extremely important to the ocean because their excreta from eating coral creates a type of sand that can keep reefs from the overgrowth of algae. So all in all they are both a pretty fish to look at and important to our ecosystem.
